WebJul 19, 2024 · 1. Using induction on the inequality directly is not helpful, because f(n) < 1 does not say how close the f(n) is to 1, so there is no reason it should imply that f(n + 1) < … WebJun 8, 2024 · For the Fibonacci recurrence, a = b = 1, and the roots of x2 − x − 1 = 0 are ϕ and 1 − ϕ = − ϕ − 1. Thus, Fn is expressible as Fn = pϕn + q( − ϕ) − n We can solve for p and q by using the initial conditions F0 = 0, F1 = 1. This gives the two equations p + q = 0 pϕ + q(1 − ϕ) = 1 with the solutions p = − q = 1 √5.
